Scope

This document was developed in recognition of a need for physically smaller interfaces consistent with modern technology. When used in conjunction with TIA-562, this Standard provides a complete interface specification suitable for non-synchronous applications where full functionality is not required. TIA-561 is applicable to the interconnection of Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE) employing serial binary data interchange where a minimal number of control and information circuits are required. Scope, interface mechanical characteristics, and functional description of the interchange circuits are defin
